who is this Prince?...please explain more I'm not following you..how will he be accepted by the Jewish people ?....he will be a Jew?
This is what I don't mind and am willing to explain as much as necessary til you do get it.
The person who becomes the little horn, leader of the EU will be a Jew in order to fulfill the prophecies of the person as later down the road, he becomes the Antichrist.
Daniel 7 is about the person first emerging on the public scene as the little horn. The person becomes the leader of Europe.
In Daniel 8, after the person has been the leader of Europe for a while as the little horn, in Daniel 8:23 it says he "stands up" which is a figure of speech for saying he prepares for war.
In Daniel 8:9, he comes with a strong army to Israel from the direction of Greece, which is the eastern most country of the EU.
So we have to ask "who is he preparing for war against?" It says in Daniel 8 that he destroys many by peace. So peace is the pretense of his preparing for war. What war?
In Ezekiel 38/39, the muslims and Russia will combine to invade Israel, a unmatched invasion the size of it. The little horn will intend to either occupy Israel before Gog/Magog can materialize, although the armies are assembling, or as a posturing move in hopes of a show of force is enough to cause the muslim/russians to think twice.
Well, it ends up that Gog/Magog attacks and it is God Himself who supernaturally destroys them.
Now the little horn, leader of Europe, a superstate desperately in need for control of oil, will seize the opportunity to move into the region and take over all the oil securing it with their military - that is what is in it for the 10 kings of Europe, not that they are so supportive Israel. But the little horn will be a Jew, so it will be important to him personally to look out for Israel's survival.
When the little horn arrives in Israel and the middle east with his EU army, post Gog/Magog, he will do so as the prince who shall come in Daniel 9:26.
Although the leader of the EU superstate, he is called a prince because he has not yet been anointed (by the false prophet assumingly) as the king of Israel - Judaism anticipated mashiach, but in real terms the Antichrist.
So with all Israel's Gog/Magog enemies destroyed, the Jews will think the time of the messianic age has arrived - but there is the matter of the mashiach himself. Which the little horn will appear to them to fit the bill.
The little horn will have such a huge ego, because of his success in all areas, including becoming the leader of Europe - he himself will fancy himself as the Jewish mashiach. And will play the role.
But underlying his success is his secret involvement in the occult (kabbalah), as it says in Daniel 8, his success will not be in his own power.
24 And his power shall be mighty,
but not by his own power: and he shall destroy wonderfully, and shall prosper, and
practise, and shall destroy the mighty and the holy people.
To play the role of the mashiach, he will have to reinstitute the commemorative reading as required by Deuteronomy 31:11-13, which essentially confirms the Mt. Sinai covenant that the promised land belongs to the Children of Israel forever. In the text of that passage, it has to be done on a 7 year cycle. Hence the confirming of the covenant for 7 years in Daniel 9:26.
Anointed as the King of Israel, the former little horn, who became the prince who shall come, operates as the King of Israel for about 3 1/2 years, causing the Jews to say and think peace, peace.... but there will be no long term peace during this false messianic age.....
Because near the middle of the 7 years, because of his occult involvement, the person will think he has achieved God-hood and goes into the temple to commit the heinous act of claiming to be God.
Which that will mortify the Jews that their mashiach would do such a thing and they will drop him as their king like a hot potato. The man of sin, as he as just revealed himself, will be enraged by their rejection and will persecute the Jews until the day that Jesus returns to rescue them.
So hopefully, you can see the false messiah age, as that first 3 1/2 years of the 7 years. The second 3 1/2 years, the person is no longer embraced by the Jews as their messiah, and it will be a time of trouble unmatched in history.
